WASHER AND DRIER- Warren 0. Paulson and Albert Kelley, International Falls, Minn.

1 Claim.

This invention appertains to new and useful improvements in washing and drying apparatus and more particularly to an apparatus for wash ing dishes and like utensils.

The principal object of the present invention is to provide an electric washer which in construction is adapted to thoroughly wash dishes and like articles in a minimum period of time with a minimum of fluid, and to dry articles quickly after fluid is drained therefrom.

Another important object of the invention is to provide a washer of the character described which requires only the manipulation of control members on a control board to cause starting, stopping, heating and draining operations in the machine.

Other objects and advantages of the invention will become apparent to the reader of the fol lowing specification.

In the drawings:

Figure 1 represents a side elevational view of the apparatus broken away to disclose the tub structure therein.

Figure 2 is a vertical sectional view through the apparatus.

Figure 3 is a horizontal sectional view taken substantially on the line 3-3 of Figure 2.

Figure 4 is a side elevational view of the impeller.

Figure 5 is an end elevational view of the impeller.

Figure 6 is a top plan view of the impeller.

igure 7 is a vertical sectional view through the implement containing basket.

Referring to the drawings wherein like numerals designate like parts, it can be seen in the drawings and especially in Figure 2, that the apparatus consists of the shell 5 having the inturned flange or ledge portion 6 at its lower edge and from the corner portions of which depend the legs 1.

Upon the ledge 6 rest the cleats 8 which are,

bridged by the platform 9 and on this platform 9 is mounted the electric motor ill which has the lateral ears ti disposed over slots i2 in the said platform with bolts l3 disposed downwardly through the cars it and slots l2 and capable of being loosened and tightened to permit adjusting and fixing of the motor ill at a definite position on the said platform 9.

Risers 14 extend upwardly from the platform 9 to support the tub generally referred to by numeral l5. This tub l5 consists in construction of the sheet metal receptacle l6 which includes surrounding wall I! of some suitable heat insulating material held in place by bands ill.

The upper edge portion of the receptacle i6 is disposed outwardly as at H! and then upwardly and clinched over the upper edge of the shell 5 as at 20. Thus a shoulder I9 is defined at l9 upon which the packing strip 2| of the hinged lid 22 can rest. This lid 22 has a suitable latch or catch 23 and is hingedly secured in place as at 24.

In the receptacle i5 is the basket assembly generally referred to by numeral 25 and this consists of the substantially square frame 26 and the substantially centrally located annulus or ring Ribs 28 extend from the ring 21 along the bottom 2) in a radial manner and for a substantial distance up the side wall a to connect to or merge with the frame 26. These ribs 28 form a bottom or base for the dishes or other articles which are to be placed in the basket 25.

Certain of the ribs 28 and the frame 26 are connected by guard members 29. These guard members extend obliquely from the frame 26 as shown in Figure 3. Dishes, saucers etc. are held by these rails 29 and also by the short guards 30 which are arranged in pairs and are of inverted U-shape, bridging certain of the ribs 28 and these guard rails 30 are located inwardly of the guard rails 29, that is, between the guard rails 29 and the annulus 21.

The annulus or ring 21 circumscribes the upwardly tapering mesh wall 3i which is topped by the plate 32. As can be seen in Figure 2, the central portion of the bottom 1) is provided with a pocket-like structure 33 in which is located the shell 34 in which is suitable filler material in which is embedded a heating element. Numeral 35 represents an electric cord extending to the heating unit.

The heating unit 34 has an open core through which the drive shaft 31 of the motor l0 extends, the shaft 31 also being disposed through a packing gland 31a. The heating unit has a depending formation 34b adapted to rest on the bottom of the pocket-like structure, the same having a plug-like formation 36 adapted to snugly extend through an opening in the bottom of the pocketlike structure. A nut 340 is provided on the pluglike formation. The upper end of this shaft 31 is constructed to take the impeller which is generally referred to by numeral 38. (See Figures 4 and 5.) The shaft 31 extends through a sleeve 31b which is disposed through the heating unit and interposed between the bottom of the the side wall a and the bottom wall I; and. the pocket-like structure 33 and the impeller 38. This impeller 38 operates within the confines of the waif. 3i and is constructed in such a manner as to pick up the water from immediately above the heating unit 34 and to throw the same laterally in an upward direction with great velocity.

Numeral 39 represents the water drain pipe which has a valve 40 therein and this pipe connects to a laterally disposed drain formation on an outlet ii depending from the pocket-like structure 33. The valve 40 is controlled'by the handle 42 on the control panel 43, a rod 44 (see Figure 1) extending from the control handle 42 downwardly and laterally as at 45 to connect to the arm 46 on the valve 40.

Numeral 41 represents th switch knob for controlling the motor in, while th heating element in the heating unit 34 is controlled by the switch knob 48. A pilot lamp 49 indicates when the heating unit is energized.

Numeral 50 denotes a perforated or side wall slotted basket, the bottom of which is formed with an upwardly extending socket 5i for receiving the upstanding pin 52 which rises from the plate 53. This plate 53 is soldered or otherwise secured to several of the ribs 28.

As can be clearly seen in Figures 4, 5 and 6, the impeller consists in construction of a plate 54 transversely tapered in opposite directions at opposite sides of the hub formation 55 at the intermediate portion thereof.

Outwardly leaning arcuate-shaped blades 58 rise from the plate 54, these blades extending toward the ends of the plate 54 from the hub 55 in inverted relation with respect to each other so as to describe substantially the letter S. The reduced edges of the plate 54 are on th open sides of the blades 56 thus permitting the plate 54 to pick up water from immediately above the heater 34 and allow the blades 55 to throw the picked up water laterally with considerable velocity.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, sin and materials may be resorted to without departing from the spirit and scope ofthe invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A washing apparatus comprising a tub provided with a relatively small pocket in the bottom thereof, a fitting structure depending from the bottom of the pocket and consisting of a packing gland and a laterally disposed formation having a drain duct therethrough, a drive shaft disposed through th packing gland and upwardly through the pocket, an annular heating unit circumscribing the drive shaft and located in the pocket, an impeller at the upper end of the drive shaft Just above the pocket, a spacing sleeve disposed through the annular heating unit and spaced therefrom and being interposed between the bottom of the pocket and said impeller, said heating unit being provided with a short depending formation adapted to rest on the bottom of the pocket to space the heating unit from the bottom of the pocket, said heating unit being of a size permitting a, space to exist between the side portion thereof and the side of the pocket, a plug formation depending from the depending formation on the heating unit and adapted to extend through an opening in the bottom of the pocket to depend a distance below the bottom of the pocket and through an opening in the fitting, a nut on the plug formation adapted to be fed against the fitting to hold the fitting and pocket together, said plug formation and formation depending from the heating unit having a conductor duct therethrough, and a drain conduit extending from the said laterally disposed formation of the fitting.
